To all-whomitmay concerm v j Be it known that I, AUGUSTVPZ. HEDBERG, av

States, residing at Milford, in the county of Worcester and State ofMassachusetts, have invented certain new and, useful Improvements ,in,Flying Ma-. chines, of which the following is. a speclfication. 1 H

The invention relates to aeroplanes-and mor particularly toflyingmachines of the paddle wheel type which are provided with constructionmay be resorted to without de-.

partingfrom the nature of the invention as claimed hereinafter. v h v iReferring to the drawings hereto attached, Fig. 1 represents anaeroplaneembodymg the invention in side view and Fig. 2 .is'a front view thereof,parts being broken away.

to in the following descrlptionandindicated in both views of thedrawings by like reference characters.- l The body of the machine isdesignated by the numeral 1 andv may be of'any construe-j tion oroutline and as shown is made tapering at'opposite ends and is mountedupon wheels 2, whereby landing may be made w th safety or the machinetrundled from one place to another. For proper ,steerlng, the machine isprovided with a vertical rudder 3 and a horizontal rudder 4, saidrudders being adapted to be adjusted in any well known manner. Sideplanes 5 give stability to the machine and assist materially in sustaining the same when in flight.

The lifting and propelling mechanism is disposed above the body of themachine and partakes of the nature of an aero-drum which is horizontallydisposed and comprises plates 6 and wings 7, the latter being pivotedintermediate of their ends to the plates 6 by means of shafts 8. Thewings 7 are curved and are disposed to have end portions over- FLYING MAHINE.

by means of the shaftlO so that adjustment ofthe arm 16 will effectacorresponding adjustment ofthe tracks 14 and 15.

Itis i to be understood that the parts are dupli Corresponding and likparts are referred cated at each side of the machine. Each sec torarm 16has itsedge portion'toothed, as in dicated at 17 and in mesh with a'worm'18 on a longitudinal shaft119, the two shafts 19 be'- ing geared toa; transverse shaft 20, so that both longitudinal shafts 19. and sectorarm'l6 i when it is,

may be simultaneously operated required to-adjust'the tracks 14 and 15.The

tracks 14 and 15 are ofcam shape'and havev a i a parallel'arrangement'soaszto maintain positive contact with the' wh eels 12'and 13 at everypoint in the revolution drum. The tracks 14 and 15 serve'to project tionof the drum.

The aero-drum is positively rotated and this IS accomplished by wormgearing, the

same consisting of a' worm gear 21 rotatable with each of the plates 6and a worm tatable with a vertlcal shaft 23 .journaled to thestandards9. Bevel gearing 24 coneach vertical shaft f 1 engine 25-mounted meets the lower end of 23 with the shaft of an upon the deck ofthe body 1. The worm gear 21 and aero-drumaremounted loosely on theshaft 10, so'as' to rotate freely thereon without interfering with theadjustment of the arm 16 and cam tracks 14 and 15 which as ,statedarcconnected to the shaft 10 which latter in'turn has the arms 16fastened thereto, whereby the arm 16, shaft 10 and cam tracks 14 and 15move together.

shaft 10. A suitable coinciding with the the inner end of frame 27. isconnected to 7 each of the planes 26 and depends therefrom andisfadapted *tobe adjusted forwardly and rearward'ly at its lower end tochange'the angleofltheiplanes 26 as may be required.

The .frame27 comprises a plurality of bars therefrom and passes aroundwhich are disposed to form a substantial and light-structure. A cord orrope 28 is attached to the lower end of each of the frames 27 andextends forwardly and 'rearwardly guide pulleys 29 and is wrapped abouta transverse shaft 30; Rotation of theshaft' 30 effects a move ment ofthe cord or rope 28 so as to move the frame =27 and'adjusttlieinclination of the planes 26. Both planes are'simultaneously adjustedbecause the connections employed infconjunction with one are duplicatedwith the. other and both cords or ropes 28 are simultaneously operatedby the shaft 30.

When themachine is at rest audit is required to rise,-the cam tracks 1etand 15 are adjusted to cause the wings 7 to extend horizontally, so thatupon moving downward the air beneath is compressed and as a consequencethe machine is lifted. VVhenthe machine is rising, the wings 7 beginto'project horizontally from the upper portion of the aero-drum and tofoldafter reaching the lower portion of the aero-drum and whiletravelling from the lower to the upper position. After the machine hasrisen to the required elevation, it is propelled by means of the'aero-drum by adjusting the cam tracks 14L and 15 so as to project thewings vertically upon the forward side of the drum and during theirtravel from front'to rear, said wings folding upon the rear andtop sideoffthe drum during such Planes 26 project laterally from the ma-' chineand are adapted to tilt about an axis time. It is also obvious that thecam tracks 14 and 15 may be adjusted so that advantage may be taken ofthe wings to controlthe descent of the machine when it is required tomake a landing. By proper adjustment be projected from the drum and'foldthereagainst at any point in the revolution of the drum, whereby tocontrol the ascent, the

flight and the descent of the machine, as will be readily understood. i

The foregoing description and the draw-' ings have reference to what maybe con I sidered the preferred, or approved form of my invention.

It is to be understood that I of the cam tracks 1a and 15, the wings may1 may make such changes in construction and arrangement and combinationof parts, ma
